The final hours of the last WGC Dell Technologies Match Play turned into a dud for everyone but Sam Burns.

Burns went on a tear Sunday afternoon in the championship match with eight birdies on his final 10 holes and enough help from Cameron Young for a 6-and-5 victory. It was the second-largest margin in an 18-hole match in this tournament.

Burns won for the fifth time on the PGA Tour. Young, who had a late rally with clutch birdies to eliminate Rory McIlroy in the semifinals, had to settle for his sixth runner-up finish in the last 18 months.

“What a week,” said Burn, who moved up to No. 10 in the world. “I’m so tired.”

Burns made it to the championship match only when defending champ Scottie Scheffler missed a 4-foot birdie putt on the 20th hole of their semifinal match. Given new life, Burns made birdie from a fairway bunker with a 15-foot putt to advance.

Young had an early lead. Burns squared the match on the fifth hole and took the lead with a chip-and-putt birdie on the par-5 sixth. And then on the next hole, Young missed a 6-foot par putt to fall 2 down. It was his first bogey since the seventh hole on Thursday.

All the momentum Young had built up over the week seemed to vanish. And the silky putting stroke of Burns was never better.

He holed a 20-foot birdie putt at No. 8. He made a 12-footer on No. 10 to go 4 up. He birdied the 11th hole from 25 feet — Young made his from 20 to halve the hole — and then it ended so abruptly.

Young pulled his shot from rough into the water on the par-5 12th, and then he came up short of the green and into the water on the reachable par-4 13th.

Burns chipped to just inside 3 feet, and Young removed his cap without making him putt.

“It’s easy to think you’re so close,” Young said. “There’s one guy standing between you and winning the tournament. And that one guy is Sam Burns playing really well.”

The highlight was his semifinal win over McIlroy, who was in full flight for so much of the week. McIlroy was 2 up with three holes to play when Young won the 16th with a birdie and then hit a nifty pitch-and-run up the slope and his purest putt of the week.

On the first extra hole at the par-5 12th, Young was in such a bad spot in the bunker next to the lip that he could only blast out to 169 yards with McIlroy just over 200 yards for his second. Young hammered pitching wedge to 9 feet and made birdie. McIlroy played short and right of the green, chipped to just inside 9 feet and missed.

Scheffler was trying to join Tiger Woods as the only back-to-back winners, and he had a 2-up lead over Burns through 10 holes.

Burns rallied back against his best friend on tour, and Scheffler had to get up-and-down from short of the 18th green for birdie to force overtime. He had it won on the second extra hole at No. 13 — except he missed the putt — and Burns escaped.

Match Play will not be on the schedule in 2024 as the PGA Tour moves toward elevated events for the top 70 or so players, a response to the threat of LIV Golf.

PGA Tour

Matt Wallace ran off four straight birdies down the stretch en route to winning his first tour title at the Corales Punta Cana Championship.

Wallace, who finished with a 6-under 66, was on the putting green when Nicolai Hojgaard, the 22-year-old playing on a sponsor exemption, had a 20-foot birdie putt on the 18th that would have forced a playoff. The putt just missed on the low side, giving the Dane a 68.

Wallace, already a four-time winner on the European tour, finished at 19-under 269 in winning in his 80th career start on the PGA Tour.

Tyler Duncan (68) and PGA Tour rookie Sam Stevens (69) tied for third.

LPGA Tour

Celine Boutier beat Georgia Hall with a birdie on the first playoff hole to win the LPGA Drive on Championship.

Boutier forced a playoff by making a testy birdie putt at the par-5 18th to close out a 4-under 68, matching Hall (65) at 20-under 268 in the tour’s first full-field event of the season.

Ayaka Furue was third at 19 under.

PGA Tour Champions

David Toms fired a 7-under 65 for a four-stroke, wire-to-wire win at The Galleri Classic to become the first two-time winner on tour this season.

The win vaulted Toms into first place in the Charles Schwab Cup standings.

Steven Alker finished alone in second, and Retief Goosen and Paul Stankowski tied for third.
